Instead of separate accessors for the segment selector and cached descriptor, use one accessor for both. This simplifies the code somewhat. Signed-off-by: NAvi Kivity <avi@redhat.com>

The last_guest_tsc is used in vcpu_load to adjust the tsc_offset since tsc-scaling is merged. So the last_guest_tsc needs to be updated in vcpu_put instead of the the last_host_tsc. This is fixed with this patch.

Currently we sync registers back and forth before/after exiting to userspace for IO, but during IO device model shouldn't need to read/write the registers, so we can as well skip those sync points. The only exaception is broken vmware backdor interface. The new code sync registers content during IO only if registers are read from/written to by userspace in the middle of the IO operation and this almost never happens in practise.

The calculation of the tsc_delta value to ensure a forward-going tsc for the guest is a function of the host-tsc. This works as long as the guests tsc_khz is equal to the hosts tsc_khz. With tsc-scaling hardware support this is not longer true and the tsc_delta needs to be calculated using guest_tsc values.

由 Avi Kivity 提交于
When running in guest mode, certain instructions can be intercepted by hardware. This also holds for nested guests running on emulated virtualization hardware, in particular instructions emulated by kvm itself. This patch adds a framework for intercepting instructions. If an instruction is marked for interception, and if we're running in guest mode, a callback is called to check whether an intercept is needed or not. The callback is called at three points in time: immediately after beginning execution, after checking privilge exceptions, and after checking memory exception. This suits the different interception points defined for different instructions and for the various virtualization instruction sets. In addition, a new X86EMUL_INTERCEPT is defined, which any callback or memory access may define, allowing the more complicated intercepts to be implemented in existing callbacks.

Since sse instructions can issue 16-byte mmios, we need to support them. We can't increase the kvm_run mmio buffer size to 16 bytes without breaking compatibility, so instead we break the large mmios into two smaller 8-byte ones. Since the bus is 64-bit we aren't breaking any atomicity guarantees. Signed-off-by: NAvi Kivity <avi@redhat.com>

If KVM cannot find an exact match for a requested CPUID leaf, the code will try to find the closest match instead of simply confessing it's failure. The implementation was meant to satisfy the CPUID specification, but did not properly check for extended and standard leaves and also didn't account for the index subleaf. Beside that this rule only applies to CPUID intercepts, which is not the only user of the kvm_find_cpuid_entry() function. So fix this algorithm and call it from kvm_emulate_cpuid(). This fixes a crash of newer Linux kernels as KVM guests on AMD Bulldozer CPUs, where bogus values were returned in response to a CPUID intercept.

When KVM scans the 0xD CPUID leaf for propagating the XSAVE save area leaves, it assumes that the leaves are contigious and stops at the first zero one. On AMD hardware there is a gap, though, as LWP uses leaf 62 to announce it's state save area. So lets iterate through all 64 possible leaves and simply skip zero ones to also cover later features.
